HOISTING AND CONVEYING DEVICE.

' i Application filed July 2,

To all whom it may concern: 1

Be it; known that I, DONALD S. ANDREWS, a. citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Hoisting and Conveying Devices, (Case 1),) of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to hoisting and conveying machines and consists of a modification of the device shown, described and claimed in my pending application Serial No. 448,437, filed February 28th, 1921.

The said invention consists of means hereinafter described and particularly set forth in the claims.

The object of my present invention is to provide a structure of the general type disclosed in my above mentioned application which may be adapted to certain specific requirements, as will be well understood by those skilled in the art.

-The annexed drawings and the following description set forth in detail certain means embodying my invention, the described means, however, constituting but one of the various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings:

Figure 1 represents a side elevation of a device embodying my present invention.

Figure 2 represents a fragmentary section taken upon the plane indicated by the line 11-11, Figure 1. a

Figure 3 represents a vertical longitudinal central section, parts, however, cut by a plane of section being shown. in elevation, such planes of section being indicated by the lines TIL-III, Figure at.

Figure 4. represents a horizontal section taken upon the plane indicated by the line IV-IV, Figure 3.

The illustrated embodiment of my inven tion comprises a monorail track 1- upon which travels a carriage or truck 2. Upon this truck is mounted a suitable electrically driven motor 3, which, through the medium of suitable gearing and other connections, is adapted to drive the traction wheels at so as to propel the truck along said track, as will be readily understood.

bars 5. 5--f0rm a part of the truck frame and fixedly secured to these channel-bars, Figure 3, is the base of a vertical mast 6, the upper end of which is provided with an antifriction roller 7 which travels between two side angle-bars 88 supported from a horizontal channel 9 which is secured to the lower flange of an Lbeam 10, the latter being suitably supported from above.

The structure thus far described is simi lar to that of the above mentioned pending application.

The base of the mast is provided with a flange 11 upon which rests the bottom of a sleeve 12 which surrounds the lower part of the mast, suitable ball-bearings 13 being interposed between said flange and sleeve as shown in Figure 3. A second ball-bearing 14 is interposed laterally between the mast and said sleeve for receiving side thrust. Fixedly secured to the lower end of the sleeve is a gear 15 which is engaged by a pinion 16 mounted upon a vertical shaft 17 to which is fixed a worm-wheel 18 engaged by a worm 19 mounted upon a shaft 20 which is rotated, through suitable gearing, by a second motor 21 mounted upon the truck.

The upper end of the sleeve 12 is also provided. with a ball-bearing 22 for receiving side thrust. Formed upon the lower portion of the sleeve are lugs 23 in which is mounted a horizontal pin 24 upon which latter is mounted an oscillatory boom 25. The outer or free end of this boom is raised or lowered by means of a cable 26 mounted upon a drum 27 and actuated through suitable intermediate gearing by a motor 28 mounted upon the sleeve. A block and fall 29 is actuated through the medium of a drum 30 rotated through suitable intermediate gearing by a motor 31, also mounted upon said sleeve.

It will therefore be seen from the above described construction that the entire device may be moved along the track 1, the boom rotated around the axis of the mast and also raised or lowered as may be desired.

What I claim is:

1. In a hoisting and conveying device, the combination of a ground track; a truck adapted to travel upon said track; a vertical mast mounted upon said truck; an overhead support for said mast; a sleeve mounted upon the latter, rotatable thereon but vertically fixed; an oscillatory boom mounted upon said sleeve; means for rotating the latter;

and means for actuating said truck to travel upon said track.

2. In a hoisting and conveying device,the combination of a ground track; a truck adapted to travel upon said track; a vertical mast mounted upon said true-k; an overhead support for said mast 1n movable engage- I ment therewith; a sleeve mounted upon the latter, rotatable thereon but vertically fixed; an oscillatory boom mounted upon said sleeve; means for rotating the latter; and means for actuating said truck to travel upon said track.
